正确选择遮阳伞的注意事项介绍

来源://www.shmtd.com/ 日期:2024-03-13 发布人:

一、遮阳伞的材料:应是能够阻挡紫外线(UV)的物质,好是缎子、涤纶或其他的微纤维材料。如果为了起见,可以选择涤纶材料。一般材料/面料越厚,提供的保护就越好。从遮阳与防紫外线的效果来看,建议选用表面为双遮阳布的遮阳伞,因为两层之间的隔热效果,伞下温度很难上升,这样可以保护我们的皮肤。同时,双层布的遮阳伞过滤紫外线效果也比单层布的要好。

1、 The material of the sunshade umbrella should be a substance that can block ultraviolet rays (UV), such as satin, polyester, or other microfiber materials. If for safety reasons, polyester material can be chosen. The thicker the material/fabric, the better the protection provided. From the perspective of shading and UV protection effects, it is recommended to choose a sunshade umbrella with a double sunshade cloth surface, because the insulation effect between the two layers makes it difficult for the temperature under the umbrella to rise, which can protect our skin. Meanwhile, the sunshade umbrella made of double-layer fabric also has better UV filtering effect than that of single-layer fabric.

二、遮阳伞的颜色:任何有紫外线防护指数的伞都有阻挡有害辐射的能力,不过在面料相同的情况下,深色的伞防紫外线效果更好,一般深色的伞布可以遮挡掉95%的UVA。

2、 The color of sunshade umbrellas: Any umbrella with a UV protection index has the ability to block harmful radiation. However, when the fabric is the same, dark umbrellas have better UV protection effects. Generally, dark umbrella fabrics can block 95% of UVA.

UVA波段是紫外线波长划分的一部分,波长320~420nm,又称为长波黑斑效应紫外线,它有很强的穿透力,UVA可以直达肌肤的真皮层,破坏弹性纤维和胶原蛋白纤维,将皮肤晒黑。黑色纤维材料的伞比其他的伞的遮挡UVA的效果更突出。因为黑色可以大限度地吸收光线。其实,除了直射的阳光紫外线外,地面反射的紫外线也会灼伤皮肤,黑伞也可以吸收地面反射的紫外线。

The UVA band is a part of the wavelength division of ultraviolet radiation, with wavelengths ranging from 320 to 420nm, also known as long wave black spot effect ultraviolet radiation. It has strong penetration power and can directly reach the dermis of the skin, damaging elastic fibers and collagen fibers, and tanning the skin. Umbrellas made of black fiber material have a more prominent effect in blocking UVA than other umbrellas. Because black can absorb light to the fullest extent. In fact, in addition to direct sunlight and ultraviolet rays, the reflected ultraviolet rays from the ground can also burn the skin, and black umbrellas can absorb the reflected ultraviolet rays from the ground.

三、遮阳伞的防晒指数(UPF):确保你买的伞有必要的“保护标记”。要知道,任何紫外线防晒指数大于30 (UPF 30+)的材料,以及限制紫外线穿透在5%或更少的范围内的遮阳伞都能起到抵御紫外线辐射的作用。旅行时,要使用UPF 50+的遮阳伞。当然,UPF值够用就好,不要一味听卖家忽悠。另外,买高UPF的伞好让卖家出示下检验报告,尤其网购的时候,防止花冤枉钱。

3、 Sun Protection Index (UPF) of Umbrella: Ensure that the umbrella you buy has the necessary "protective markings". It should be noted that any material with a UV sun protection index greater than 30 (UPF 30+), as well as sunshades that limit UV penetration to 5% or less, can resist UV radiation. When traveling, use a UPF 50+sunshade umbrella. Of course, as long as the UPF value is sufficient, don't just listen to the seller's deception. In addition, buying umbrellas with high UPF allows sellers to present inspection reports, especially when shopping online, to prevent wasting money.

四、遮阳伞的涂层:伞的反射面积很大,伞布内面好有黑色的涂层,以避免再次反射地面的UVA脸部。现在市面上的遮阳伞多以黑胶为主,银胶相对于黑胶而言,具有容易脱落、防晒效果一般的缺点,而品质好的黑胶透光率可以达到几乎为0,劣质的黑胶涂层可能含有致癌物质,对身体造成伤害。遮阳伞中涂层主要是增加抗紫外线的功能,其实质的抗紫外线的物质主要是二氧化钛。

4、 Coating for sunshade umbrellas: The umbrella has a large reflective area, and the inner surface of the umbrella fabric should have a black coating to avoid reflecting UVA from the ground to the face again. Nowadays, sunshade umbrellas on the market are mainly made of black glue. Compared to black glue, silver glue has the disadvantages of easy detachment and average sun protection effect. However, high-quality black glue can have a light transmittance of almost 0, and low-quality black glue coatings may contain carcinogens, which can cause harm to the body. The main function of the coating in sunshades is to increase their UV resistance, and its essential anti UV material is mainly titanium dioxide.

现在市场上宣传的纳米涂层也就是在织物纤维的内部掺入吸收紫外线的材料,或是在织物完成以后做后期整理,渗入一些吸收紫外线的材料,如纳米级的氧化锌或二氧化钛等,并无其他特别之处,所以关键仍然是遮阳伞中抗紫外线物质的含量的多少。综合以上所有建议好选择黑胶涂层的遮阳伞。

The nano coating currently promoted in the market refers to the addition of materials that absorb ultraviolet rays into the interior of fabric fibers, or the infiltration of some materials that absorb ultraviolet rays after finishing the fabric, such as nanoscale zinc oxide or titanium dioxide, without any other special features. Therefore, the key is still the amount of anti ultraviolet substances in the sunshade umbrella. Based on all the above suggestions, it is recommended to choose a sunshade umbrella with a black adhesive coating.

五、遮阳伞的大小:当你在长期在户外选择撑伞的时候,要选择直径较大的伞,以提供大的保护和小的曝光量。因为紫外线是从各个方向照射的,所以面积越大,能抵挡紫外线的效果越好。所以,挑选时好撑开看看面积大小。这也是为什么我们即使打着遮阳伞,依然要涂防晒霜的原因。

5、 The size of a sunshade umbrella: When choosing to hold an umbrella outdoors for a long time, choose an umbrella with a larger diameter to provide greater protection and lower exposure. Because ultraviolet rays are irradiated from all directions, the larger the area, the better the ability to resist ultraviolet rays. So, when choosing, it's good to spread it out and see the size of the area. This is also why we still need to apply sunscreen even when holding a sunshade umbrella.

六、伞架或伞骨:伞架或伞骨是使遮阳伞保持稳定的。伞架是伞的核心部件,好的伞架要做到防锈、轻便、牢固、推拉顺畅。就材料而言,好的材料应该是碳纤维,轻而坚固;其次是铝合金,也是现在市面上多的一种。另外,中杆截面的边越多越好,双层套管比单层好。

6、 Umbrella frame or ribs: Umbrella frames or ribs are used to keep sunshades stable. The umbrella frame is the core component of an umbrella, and a good umbrella frame should be rust proof, lightweight, sturdy, and smoothly pushed and pulled. In terms of materials, a good material should be carbon fiber, which is light and sturdy; Next is aluminum alloy, which is also one of the most common types on the market today. In addition, the more edges in the cross-section of the middle rod, the better, and double-layer casing is better than single-layer casing.
